To LUZ whmn it may concern:

Be it known that we, DENNIS S. BLUE and OTIS SHEPARDSON, citizens of theUnited States, and residents of Fremont. in the county of Sandusky andState of Ohio, have invented.

a new and useful Improvement in Cultivators, of which the following is aspecification.

Our invention relates to an improvement in cultivators, and itsupplements some of the features disclosed in Letters Patent N 0.628,745, granted to Dennis S. Blue July 11, 1899.

One of the principal objects of our present invention is to providemeans within the drivers control for cultivating crooked rows or placeswhere the rows are not perfectly straight with the same facility thatstraight rows are cultivated.

A further object is to provide means for turning and slanting thecultivator-gangs or for shifting them laterally bodily and for applyingpressure to the gangs to increase the depth to which they shouldpenetrate the soil.

Still another object is to provide means whereby the cultivator-gangsmay be operateril1 and controlled either by hand or foot, or bot \Viththese objects in view our present invention consists in foot-levers ortreadles pivotally supported upon the cultivator-gangs, in combinationwith a pivotally-supported arch,

whereby the gangs are coupled together and made to operate in unisonwith each other.

Our invention further consists in the above mechanism in connection witha hand-lever, whereby the gangs may be controlled by hand or foot, orboth; and it still further consists in certain novel features ofconstruction and combinations of parts, which will be hereinafthedescribed, and pointed out in the claims. In the accompanying drawings,Figure 1 is a plan View. Fig. 2 is a side elevation. Fig. 3 is a frontview. Fig. 4 is a view in perspective of the several novel features foraccomplishing the objects set forth, and Fig. 5 is a detail view of thelever-and-plate connection.

Arepresents a U-shaped frame; B, the axle to which the frame isconnected and upon which it is supported.

U C are the wheels, in the hubs of which the ends of the axle arejournaled, and D is the tongue or pole attached to the axle and forwardportion of the U-shaped frame. An auxiliary frame E straddles the tongueor pole and depends therefrom just forward'of the U- shaped frame and atits lower ends is provided with outwardly extending guiderods, the outerends of which are connected with the frame A and axle B by braces land2, respectively, the latter of which are adjustably connected with theaxles by means of the racks 3 3 and the cams 4 4:.

G G are the cultivator-gangs, comprising each as many beams 5 5 as thereare cultivator-shovels 6 6, which latter are secured thereto in anyapproved manner. The forward ends of these gangs have sliding connectionwith the guide-rods 7 7 of the auxiliary frame E and are connectedtogether by means of the yoke 8, which extends upward preferably justslightly below the tongue or pole.

Foot-levers or treadles F F are pivoted intel-mediate their ends betweenthe inner beams 5 5 of each of the two gangs,preferably on a pin orbolt9, the ends of which are secured in said beams of each gang. The rearends of these foot-levers or treadles extend rearward within easy reachof the drivers feet when the driver is seated in the seat S.Incidentally these footlevers or treadles afford arest for the driversfeet at all times, although primarily this is not their most importantfunction, as will be explained presently. The forward ends of thesefoot-levers or treadles are provided with the upwardly-extending arms 1010. To the upper ends of the arms the rear ends of rods 11 11 arejournaled, and the forward ends of these rods are hooked into holes 1212 in the arch 13. -A segment 14is secured to this arch, and a lever 15,secured intermediate its ends to the segment and arch, is pivotallysupported by a pin or bolt 18 to the center of the hanger 19, whichlatter is adjustably connected, by means of holes 16 16 and bolts 17 17,to the tongue or pole above, the segment serving to brace and strengthenboth lever and arch relative to one another. The forward end of thelever 15 extends loosely through a hole 20 in a plate 21, bolted orotherwise secured to the center of the yoke 8. A hand-lever 22, securedto the rear end of lever 15, extends rearwardly within reach of thedriver.

rom the foregoing it will be observed that to an elevation.

two different means areprovided by which the driver may control thecultivator-gang,

one being the hand-lever 22 and the other and pressing down upon both ofthem equally he is enabled to apply pressure to them to regulate thedepth of penetration. By pressing upon the right-hand treadle it swingsthe right-hand end of the arch rearward and the yoke 8 to the right,thus swinging the two gangs diagonally and with their forward endstoward the right side of the cultivator. By pressing on the left-handfoot-lever or treadle the gangs are shifted simultaneously a to theother side, a similar action taking place asbefore, only in reverse. Inlike manner by swinging the hand-lever to the left the forward ends ofthe gang are shifted to the right, and by swinging the hand-lever to theright they in turn are moved to the left. It is also possible for thedriver to shift the rear ends of the gang laterally to the right or leftby simply pushing the foot when on the treadle in either direction.Either gang might be depressed without the other by holding thehand-lever at the center point and by pressing either foot as therequirements demand it.

The gangs are raised and lowered in the usual manner by the hand-levers25 operating on segments 26 26 through chains or flexible connections 2727.

From the foregoing it will be seen that the driver is able to exerciseperfect control over the cultivator-gangs at all times, so that acrooked row may be cultivated with as much ease and with practically thesame degree of perfection that a straight row may be cultivated, as thegangs either independently or together are rendered perfectly sensitiveto the drivers wishes.

It is evident that slight changes might be made in the form andarrangement of the several parts described without departing from thespirit and scope of ourinvention,and hence we do not wish to limitourselves to the exact construction herein set forth; but,

Having fully described our invention, what we claim as new, and desireto secure by Letters Patent, is

1. In a cultivator, the combination with a frame, and laterally-movablegangs, of a handlever pivotally secured at a point intermediate itsends, to the frame, an arch rigidly secured to the hand-lever at a pointintermediate its ends, foot-levers pivotally carried by each of thegangs, means connecting the foot-levers and arch, and a yoke to whichthe gangs are secured, one end of the hand-lever secured to the yoke,the movement of one foot-lever operating the gangs simultaneously.

2. In a cultivator, the combination with a frame, and gangs, of alaterally-movable yoke to which the gangs are secured, apivotallymounted arch, means connecting the arch and yoke, foot-leverspivotally supported on each gang and means connecting the foot-leversand arch, a movement of either foot-lever adapted to simultaneouslyoperate the gangs.

3. In a cultivator, the combination with a suitable frame alaterally-movable yoke and gangs connected to the yoke, of a hangerdepending from the frame, a lever pivotally secured intermediate itsends to the hanger, one end of the lever engagingand supporting the yokeand adapted to move it laterally, an arch secured to the leverintermediate its ends, footlevers pivotally supported on the gangs andmeans connecting the foot-levers and arch whereby the actuation ofeither foot-lever will operate both gangs.

4:. In a cultivator, the combination with a suitable frame, alaterally-movable yoke, and gangs connected to the yoke, of apivotallysupported arch, means connecting the arch and yoke, bell-cranklevers pivotally mounted on each of the gangs, and means connecting thebell-cranks and arch whereby the actuation of either bell-crank willsimultaneously operate both gangs.

5. In a cultivator, the combination with a suitable frame,laterally-movable yoke and gangs secured to and connected by the yoke,of a lever pivotally secured intermediate its ends to the frame, one endof the lever engaging and supporting the yoke, an arch secured to thelever, and foot-levers carried by each of the gangs and connected withthe arch, the operation of one of the foot-levers adapted to move thearch and simultaneously operate the gangs.

6. In a cultivator, the combination with a frame, a laterally-movingyoke and gangs secured to and connected by the yoke, of a leverpivotally secured intermediate its ends to the frame, one end of thelever loosely secured to the yoke, an arch carried by the lever,footlevers pivotally mounted on each gang and connected with the archand a hand-lever secured to the lever which extends to the yoke, thegangs being movable simultaneously by means of the hand-lever or eitherfoot-lever.

7. In a cultivator, the combination with a frame, a laterally-movableinverted-U-shaped yoke and gangs connected to the yoke, of a leverpivotally supported on the frame and connected to the yoke to shift thelatter laterally, an inverted-U-shaped arch carried by and moving withthe lever, and means carried by the gangs and connected with the yokefor simultaneously moving the gangs.
